Welcome to Theoretical Nanophysics
We explore light-matter interaction at the nanoscale by theoretical and computational means. Our aim is to enhance and to control this interaction by resonant phenomena using metallic and dielectric resonators as well as open cavities and waveguides. We investigate various applications in the linear and nonlinear regime, including optical sensors for chiral and achiral materials.
